The name of the Corporation is Doane Pet Care Company. 2. Pursuant to a Certificate of Designations, Preferences and Rights filed by the Corporation or officers thereof October 4, 1995, a series of the Corporation's preferred stock, $0.01 per share was created and designated as the 14.25% Senior Exchangeable Preferred Stock Due 2007 (the "Original Certificate of Designations"). 3. This Certificate of Amendment to the Certificate of Designations amends the Original Certificate of Designations in its entirety. 4. The text of this Certificate of Amendment to the Certificate of Designations as so amended provides in its entirety as follows: (1) NUMBER AND DESIGNATION. 3,000,000 shares of the Preferred Stock of the Corporation shall be designated as 14.25% Senior Preferred Stock Due 2007 (the "SENIOR PREFERRED STOCK"). (2) RANK. The Senior Preferred Stock shall, with respect to dividend rights and rights on liquidation, dissolution and winding up, rank prior to all classes of the or series of common stock of the Corporation, including the Corporation's Class A or Class B common stock, $0.0001 par value ("COMMON STOCK") and each other class of capital stock of the Corporation, the terms of which provide that such class shall rank junior to the Senior Preferred Stock or the terms of which do not specify any rank relative to the Senior Preferred Stock. All equity securities of the Corporation to which the Senior Preferred Stock ranks prior (whether with respect to dividends or upon liquidation, dissolution, winding up or otherwise), including the Common Stock, are collectively referred to herein as the "JUNIOR SECURITIES." All equity securities of the Corporation with which the Senior Preferred Stock ranks on a parity (whether with respect to dividends or upon liquidation, dissolution or winding up) are collectively referred to herein as the "PARITY SECURITIES." The respective definitions of Junior Securities and Parity Securities shall also include any rights or options exercisable for or convertible into any of the Junior Securities and Parity Securities, as the case may be. The Senior Preferred Stock shall be subject to the creation of Junior Securities and Parity Securities. (3) DIVIDENDS. (a) (i) The holders of shares of shares of Senior Preferred Stock shall be entitled to receive, when, as and if declared by the Board of Directors, out of funds legally available for the payment of dividends, dividends (subject to Sections 3(a)(ii) and (iii) hereof) at the rate of 14.25% per annum (computed on the basis of a 360 day year) (the "DIVIDEND RATE") on the Liquidation Value of each share of Senior Preferred Stock on and as of the most recent Dividend Payment Date (as defined below). In the event the Corporation is unable or shall fail to discharge its obligation to redeem all outstanding shares of Senior Preferred Stock pursuant to paragraph 5(c) or 5(d) hereof, the Dividend Rate shall increase by .25 percent per quarter (each, a "DEFAULT DIVIDEND") for each quarter or portion thereof following the date on which such redemption was required to be made until cured, provided that the aggregate increase shall not exceed 3%. Such dividends shall be payable in the manner set forth below in Sections 3(a)(ii) and (iii) quarterly on March 31, June 30, September 30, and December 31 of each year (unless such day is not a business day, in which event on the next succeeding business day) (each of such dates being a "DIVIDEND PAYMENT DATE" and each such quarterly period being a "DIVIDEND Period"). Such dividends shall be cumulative from the date of issue, whether or not in any Dividend Period or Periods there shall be funds of the Corporation legally available for the payment of such dividends. (ii) Prior to October 5, 2000 (the "CASH PAY DATE"), dividends shall not be payable in cash to holders of shares of Senior Preferred Stock but shall, subject to Section 3(b) hereof, accrete to the Liquidation Value in accordance with Section 4(a) hereof. (iii) Following the Cash Pay Date, each such dividend shall be payable in cash on the Liquidation Value per share of the Senior Preferred Stock, in equal quarterly amounts, (to which the Default Dividend, if any, shall be added) to the holders of record of shares of the Senior Preferred Stock, as they appear on the stock records of the Corporation at the close of business on such record dates, not more than 60 days or less than 10 days preceding the payment dates thereof, as shall be fixed by the Board of Directors. Accrued and unpaid dividends for any past Dividend Periods may be declared and paid at any time, without reference to any Dividend Payment Date, to holders of record on such date, not more than 45 days preceding the payment date thereof, as may be fixed by the Board of Directors. (b) At the written request of the holders of a majority of the shares of Senior Preferred Stock (provided, that at the time such request is made, DLJ Merchant Banking Funding, Inc. or any of its affiliates shall not own any shares of Senior Preferred Stock), the Corporation shall, commencing on the first Dividend Payment Date after such request and ending on the Cash Pay Date, be required to pay all dividends on shares of Senior Preferred Stock by the issuance of additional shares of Senior Preferred Stock ("ADDITIONAL SHARES"). The Additional Shares shall be identical to all other shares of Senior Preferred Stock, except as set forth in Section 4. For the purposes of determining the number of Additional Shares to be issued as -2- dividends pursuant to this Paragraph (b), such Additional Shares shall be valued at their Applicable Liquidation Value as provided in Section 4(c). (c) Holders of shares of Senior Preferred Stock shall not be entitled to any dividends, whether payable in cash, property or stock, in excess of the cumulative dividends, as herein provided, on the Senior Preferred Stock. Except as provided in this Section 3, no interest, or sum of money in lieu of interest, shall be payable in respect of any dividend payment or payments on the Senior Preferred Stock that may be in arrears. (d) So long as any shares of the Senior Preferred Stock are outstanding, no dividends, except as described in the next succeeding sentence, shall be declared or paid or set apart for payment on Parity Securities, for any period unless full cumulative dividends have been or contemporaneously are declared and paid or declared and a sum sufficient for the payment thereof set apart for such payment on the Senior Preferred Stock for all Dividend Periods terminating on or prior to the date of payment of the dividend on such class or series of Parity Securities. When dividends are not paid in full or a sum sufficient for such payment is not set apart, as aforesaid, all dividends declared upon shares of the Senior Preferred Stock and all dividends declared upon any other class or series of Parity Securities shall be declared ratably in proportion to the respective amounts of dividends accumulated and unpaid on the Senior Preferred Stock and accumulated and unpaid on such Parity Securities. (e) So long as any shares of the Senior Preferred Stock are outstanding, no dividends (other than dividends or distributions paid in shares of, or options, warrants or rights to subscribe for or purchase shares of, Junior Securities) shall be declared or paid or set apart for payment or other distribution declared or made upon Junior Securities, nor shall any Junior Securities be redeemed, purchased or otherwise acquired (other than a redemption, purchase or other acquisition of shares of Common Stock made for purposes of an employee incentive or benefit plan of the Corporation or any subsidiary) (all such dividends, distributions, redemptions or purchases being hereinafter referred to as a "JUNIOR SECURITIES DISTRIBUTION") for any consideration (or any moneys be paid to or made available for a sinking fund for the redemption of any shares of any such stock) by the Corporation, directly or indirectly (except by conversion into or exchange for Junior Securities), unless in each case (i) the full cumulative dividends on all outstanding shares of the Senior Preferred Stock and any other Parity Securities shall have been paid or set apart for payment for all past Dividend Periods with respect to the Senior Preferred Stock and all past dividend periods with respect to such Parity Securities and (ii) sufficient funds shall have been paid or set apart for the payment of the dividend for the current Dividend Period with respect to the Senior Preferred Stock and the current dividend period with respect to such Parity Securities. (4) LIQUIDATION PREFERENCE. (a) In the event of any liquidation, dissolution or winding up of the Corporation, whether voluntary or involuntary, before any payment or distribution of the -3- assets of the Corporation (whether capital or surplus) shall be made to or set apart for the holders of Junior Securities, the holders of the shares of Senior Preferred Stock shall be entitled to receive an amount equal to the Liquidation Value of such share plus any accrued and unpaid cash dividends to the date of distribution. "LIQUIDATION VALUE" on any date means, with respect to (x) any share of Senior Preferred Stock other than any Additional Shares, the sum of (1) $25.00 and (2) the aggregate of all dividends accreted on such share until the most recent Dividend Payment Date upon which an accretion to Liquidation Value has occurred (or if such date is a Dividend Payment Date upon which an accretion to Liquidation Value has occurred, such date), provided that in the event of an actual liquidation, dissolution or winding up of the Corporation the amount referred to in (2) shall be calculated by including dividends accreting to the actual date of such liquidation, dissolution or winding up, rather than the Dividend Payment Date referred to above and provided further that in no event will dividends accrete beyond the earlier of (i) the Cash Pay Date and (ii) the most recent Dividend Payment Date prior to the Dividend Payment Date on which dividends on the Senior Preferred Stock are payable in Additional Shares and (y) any Additional Share, the Applicable Liquidation Value. All accretions to Liquidation Value will be calculated using compounding on a quarterly basis. Except as provided in the preceding sentences, holders of shares of Senior Preferred Stock shall not be entitled to any distribution in the event of liquidation, dissolution or winding up of the affairs of the Corporation. If, upon any liquidation, dissolution or winding up of the Corporation, the assets of the Corporation, or proceeds thereof, distributable among the holders of the shares of Senior Preferred Stock shall be insufficient to pay in full the preferential amount aforesaid and liquidating payments on any Parity Securities, then such assets, or the proceeds thereof, shall be distributed among the holders of shares of Senior Preferred Stock and any such other Parity Securities ratably in accordance with the respective amounts that would be payable on such shares of Senior Preferred Stock and any such other stock if all amounts payable thereon were paid in full. For the purposes of this paragraph (4), (i) a consolidation or merger of the Corporation with one or more corporations, or (ii) a sale or transfer of all or substantially all of the Corporation's assets, shall not be deemed to be a liquidation, dissolution or winding up, voluntary or involuntary, of the Corporation. (b) Subject to the rights of the holders of any Parity Securities, after payment shall have been made in full to the holders of the Senior Preferred Stock, as provided in this paragraph (4), any other series or class or classes of Junior Securities shall, subject to the respective terms and provisions (if any) applying thereto, be entitled to receive any and all assets remaining to be paid or distributed, and the holders of the Senior Preferred Stock shall not be entitled to share therein. (c) The Applicable Liquidation Value of any Additional Shares shall be the Liquidation Value of Senior Preferred Stock outstanding immediately prior to the first Dividend Payment Date occurring after a request for payment in Additional Shares has been made in accordance with Section 3(b). (d) Shares of Senior Preferred Stock issued in connection with an exchange offer made by the Corporation for outstanding shares of Senior Preferred Stock for the purpose of providing the holders of such outstanding shares of Senior Preferred Stock with shares registered under the Securities Act of 1933, as amended, shall initially have a liquidation preference equal to the Liquidation Value of such outstanding shares of Senior Preferred Stock on the date of such exchange and shall thereafter have a Liquidation Value determined in accordance with Section 4(a). -4- (5) REDEMPTION. (a) Redemption Upon Consummation of Initial Public Offering. The Corporation may, at is option, to the extent it shall have funds legally available for such payment, redeem, prior to September 30, 1998, in whole or in part, shares of Senior Preferred Stock, at a redemption price per share equal to 114% of the Liquidation Value, in cash, plus accrued and unpaid cash dividends on such share to the date fixed for redemption, without interest, provided that the Corporation shall not redeem any shares of Senior Preferred Stock pursuant to this Paragraph 5(a) unless (i) prior to such redemption an Initial Public Offering shall have been consummated, (ii) following such redemption, at least two-thirds of the number of shares of Senior Preferred Stock issued and outstanding as of the Closing Date (adjusted to reflect stock splits, stock dividends, recapitalizations or similar events) shall remain issued and outstanding following such redemption and (iii) the aggregate redemption price of the shares of Senior Preferred Stock redeemed pursuant to this Section 5(a) does not exceed the net proceeds received by the issuer in such Initial Public Offering.

(b) In the event the Corporation shall redeem shares of Senior Preferred Stock pursuant to Sections 5(a), (b) or (d), notice of such redemption shall be given by first class mail, postage prepaid, mailed not less than 30 days nor more than 60 days prior to the redemption date, to each holder of record of the shares to be redeemed at such holder's address as the same appears on the stock register of the Corporation; provided that neither the failure to give such notice nor any defect therein shall affect the validity of the giving of notice for the redemption of any share of Senior Preferred Stock to be redeemed except as to the holder to whom the Corporation has failed to give said notice or except as to the holder whose notice was defective. Each such notice shall state: (i) the redemption date; (ii) the number of shares of Senior Preferred Stock to be redeemed and, if fewer than all the shares held by such holder are to be redeemed, the number of shares to be redeemed from such holder; (iii) the redemption price; (iv) the place or places where certificates for such shares are to be surrendered for payment of the redemption price; and (v) that dividends on the shares to be redeemed will cease to accrue on such redemption date.

Upon surrender in accordance with said notice of the certificates for any shares so redeemed (properly endorsed or assigned for transfer if the Board of Directors of the Corporation shall so require and the notice shall so state), such share shall be redeemed by the Corporation at the -7- redemption price aforesaid. In case fewer than all the shares represented by any such certificate are redeemed, a new certificate shall be issued representing the unredeemed shares without cost to the holder thereof. (d) In the case of a redemption pursuant to Section 5(c) hereof, notice of such redemption shall be given by first class mail, postage prepaid, mailed not more than 15 days following the occurrence of the Change of Control and not less than 30 days prior to the redemption date, to each holder of record of the shares to be redeemed at such holder's address as the same appears on the stock register of the Corporation; provided that neither the failure to give such notice nor any defect therein shall affect the validity of the giving of notice for the redemption of any share of Senior Preferred Stock to be redeemed except as to the holder to whom the Corporation has failed to give said notice or except as to the holder whose notice was defective.

Upon surrender in accordance with said notice of the certificates for any shares so redeemed (properly endorsed or assigned for transfer, if the Board of Directors of the Corporation shall so require and the notice shall so state), such share shall be redeemed by the Corporation at the redemption price aforesaid. In case fewer than all the shares represented by any such certificate are redeemed, a new certificate shall be issued representing the unredeemed shares without cost to the holder thereof.
